A method of preparing a 2,6 disubstituted anilines includes, reacting a 2-amino isophtha!ic acid diester with sufficient Grignard reagent R2CH2MgX to form the corresponding diol product, dehydrating the diol product to the corresponding dialkene; and hydrogenating the diol product to form the corresponding aniline. The 2,6 disubstituted anilines can be used to produce N-Heterocyciic Carbenes (NHCs). The NHCs can find application in various fields such as organic synthesis, catalysis and macromolecular chemistry. Palladium catalysts containing the NHCs are also described.

The development of new N-heterocycliccarbenes (NHC) is a key feature in this now mainstream research area to access novel chemical properties and reactivity that are essential for the discovery of original applications. Up to now, only a few reliable methods have proven suitable for the preparation of methoxylated anilines to ultimately access methoxylated NHC. We are pleased to report here a straightforward
